Anza recommends Agave v4.3.2 for every mainnet validator before Alpenglow
Anza calls Agave v4.3.2 the recommended version for every mainnet validator. The release carries fixes for Alpenglow in epoch 1064 on 21 October.
On 16 October, Anza named Agave v4.3.2 the recommended version for every validator on mainnet-beta. The post cites important performance and stability fixes ahead of Alpenglow in epoch 1064 on 21 October.
GitHub marks the release stable for testnet, devnet, and mainnet beta. The changelog includes “Alpenglow slot timing for transaction buffering.” On X, ashwin.sol lists three tasks: move to v4.3.2, turn vote mods off, and fund the vote account with at least 0.82 SOL for the VAT.
Anza’s documentation and the upgrade page both say 0.8 SOL above the rent-exempt minimum. The epoch 1064 report still cites a build on Agave 4.3.0.
